Abstract

Novel glasses in a Ga₂S₃-Sb₂S₃-AgI system were prepared with a melt-quenching method, and their glass-forming region was identified. The maximum dissolvable AgI in glasses was 65 mol%. The thermal, optical, and structural properties of glasses were investigated as a function of AgI and Ga₂S₃ contents. The Ga₂S₃-Sb₂S₃-AgI glasses possess a wide region of transmission window (0.65-14 μm). An ionic conductivity of approximately 1.01 × 10^-3 S/cm can be obtained for a 40 (0.8Sb₂S₃-0.2Ga₂S₃)-60AgI glass at an ambient temperature, and the ionic conductivity increased as temperature increased. The relative activation energy of Ag⁺ conduction was also calculated. These novel glasses show potential for the combined application of infrared optics and solid electrolytes.
